Merge branch 'gro-retpoline'
Alexander Lobakin says: ==================== net: avoid retpoline overhead on VLAN and TEB GRO dev_gro_receive() uses indirect calls for IP GRO functions, but it works only for the outermost headers and untagged frames. Simple VLAN tag before an IP header restores the performance hit. This simple series straightens the GRO calls for IP headers going after VLAN tag or inner Ethernet header (GENEVE, NvGRE, VxLAN) for retpolined kernels. ====================
